Research output: Contribution to journalConference articlepeer-review


In this paper we review the recent progress on the development of novel quantum-dot structures and laser devices. The investigation of novel regimes of ultrashort pulse generation in quantum-dot edge-emitting lasers will be presented. We illustrate how new functionalities have been opened up, such as dual-wavelength mode-locking and enhanced tunability, through the exploitation of the excited-state transitions in the quantum dots as an additional degree of freedom in these ultrafast lasers. Progress on novel design rules for quantum-dot based vertical external cavity lasers and SESAMs are also considered.
